derivative of

7 e^{x} arctan (x)

7 (e^{x} arctan (x) + \frac{e ^{x}}{x ^{2} + 1})

Solution steps

\frac{d}{d x} (7 e^{x} arctan (x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 7 \frac{d}{d x} (e^{x} arctan (x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = e^{x}, g = arctan (x)

= 7 (\frac{d}{d x} (e^{x}) arctan (x) + \frac{d}{d x} (arctan (x)) e^{x})

\frac{d}{d x} (e^{x}) = e^{x}

\frac{d}{d x} (arctan (x)) = \frac{1}{x ^{2} + 1}

= 7 (e^{x} arctan (x) + \frac{1}{x ^{2} + 1} e^{x})

\frac{1}{x ^{2} + 1} e^{x} = \frac{e ^{x}}{x ^{2} + 1}

= 7 (e^{x} arctan (x) + \frac{e ^{x}}{x ^{2} + 1})

t^{2} y^{^{''}} - 2 t y^{^{'}} - 4 y = 0

\frac{d}{d x} (\frac{\frac{d}{d x} ( 2 )}{x})

d er i v a t i v e y = 4 e^{x} + 4 ln (x)

\frac{d}{d x} (100 x y)

\frac{d}{d x} (x^{3} \cdot e^{- 3 x})
